【摘要】 基于精细积分和状态空间法提出了一种新的浮筏系统动态响应分析方法,并结合侧挂式浮筏系统算例对该方法进行了验算。研究表明,该方法适用性好、稳定性高、无需对系统解耦,可应用于复杂荷载和多自由度浮筏系统,而且进行数值求解时不受时间步长限制,能达到很高的计算精度。更多还原

【Abstract】 This paper proposed a new response analysis method for raft isolation system by the combination of precise integration and state-space.The numerical example of side-connection raft show that the method is convergent and need not to decouple the system.The example also indicate that the new method is not sensitive to time-step and its calculation precision can be controlled easily.So the method used to complex load and multi-degree system.更多还原
